Japanese Anime Speech Dataset

japanese-anime-speech is an audio-text dataset designed for the training of automatic speech recognition models. The dataset is comprised of thousands of audio clips and their corresponding transcriptions from different visual novels.

The goal of this dataset is to enhance the proficiency of automatic speech recognition systems, such as OpenAI's Whisper, in accurately transcribing dialogue from anime and other similar Japanese media. This genre is characterized by unique linguistic features and speech patterns that diverge from conventional Japanese speech.

A list of all audio files and transcriptions are here.

Changelog

V1 - This version contains 16,143 audio-text pairs from the visual novel IxSHE Tell. Some cleaning of the transcriptions has been done to get rid of unwanted characters at the start and end of lines, but I intend to do much more for the second version.
V2 - The version contains 23,422 audio-text pairs from three different visual novels. Cleaning has been done to remove most nsfw lines, especially noises that aren't words. The audio is now in mp3 format, rather than wav. This version contains 32.6 hours of audio.
V3 - The dataset now contains 38,325 audio-text pairs from five different visual novels. Very thorough cleaning has been done to remove almost all nsfw or low-quality audio files. Transcriptions have been formatted to contain much fewer dramatised duplicated characters (for example 「ああああーーー」), and transcriptions have been made much more consistent (for example, using the same type of quotation mark). This version contains 52.5 hours of audio.

Dataset information

38,325 audio-text pairs
52.5 hours of audio (OpenAI suggests a minimum of 5 hours for productive Whisper fine-tuning).
4.9s average audio length.
All transcriptions have been scraped directly from the game files of visual novels.

Content Warning: Please be advised that the majority of the audio in this dataset is sourced from visual novels and may include content that is not suitable for all audiences, such as suggestive sounds or mature topics. Efforts have been undertaken to minimise this content as much as possible.

To do

Create a dataset of over 10k items
Create a dataset of over 20k items
Compress the audio with minimal quality loss
Create a dataset of over 30k items
Create more workflows for scraping audio from visual novels that use an engine other than Artemis
Add audio from more visual novels
Convert names in transcriptions to katakana?

Use & Credit

This dataset is openly available for commercial or non-commercial use. Anyone is welcome to use this resource as they deem appropriate.

I hope that by sharing this dataset, we (the open-source community) improve automatic speech recognition for anime content.
